Chlorodimethylsilane Usage And Synthesis
Chemical Properties | Colorless clear liquid |
General Description | A colorless fuming liquid with a pungent, burning odor. Flash point -18°F. Boiling point 95°F. Density about 6.9 lb / gal. Extremely corrosive to skin and respiratory tissues, both as a liquid and vapor. Vapors are heavier than air. |
Air & Water Reactions | Highly flammable. Reacts violently on contact with water to liberate heat and hydrogen chloride gas. |
Reactivity Profile | Chlorosilanes, such as DIMETHYLCHLOROSILANE, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases. |
Health Hazard | May cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. |
Fire Hazard | Flammable/combustible material. May be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. |
